YOUNGSTOWN, Ohio (WKBN) — Youngstown State University history professor Donna DeBlasio has written a book called “Images of America: Youngstown.”

It goes on sale Monday.

DeBlasio said she was contacted by the publisher who said they wanted this kind of book, which features a lot of pictures. She said there are 218 photographs in the book.

Much of the book focuses on the city’s steel history, but other aspects of the city are addressed as well. DeBlasio said the purpose of the book is to show the impact of the steel industry on those other aspects.

Some of the photos date back more than 100 years. DeBlasio said she cannot recall how many photos they looked at, but believed it was close to 1,000.

She said she teamed up with the Mahoning Valley Historical Society to write the book.
